SELF-INKING HAND-STAM P.

EPECIFICATION forming part of Letters Patent No. 338,153, dated March 16, 1886.

Serial No. 138,573. (No model.)

To @ZZ whom t may concern:

Be it known that I, BENJAMIN B. HILL, a citizen of the United States of America, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvement-s in Self-Inking Hand-Stamps, of which the following is a specification, reference being had therein to the accompanying drawings.

This improvement relates more particularly to that class of self-inking stamps in which type-bands are employed; but one feature of it may be employed with movable type of other kinds, whether of the wheel form or common type.

The invention consists in the peculiar construction and arrangement of parts hereinafter more particularly described, and then pointed out iu the claims.

In the accompanying drawings, Figure l represents a front elevation of a stamp constructed according to my improvement, in

` which the bands are partially exposed. Fig.

2 represents a back elevation of a stamp of somewhat similar form, in which the bands are covered by a casing; and Fig. 3 represents an end view of the type-plate and its attachments detached from the frame,with a part broken away.

Referring now to the details of the drawings, A represents the handle, B the yoke, and C the frame, of the ordinary well-known selfinking stamp, which frame, as is well known, is provided with a slot in each side, through which works the screws or pins D, that conneet the arms b of the yokeB to the oscillating plate E, carrying a fixed inscription or type plate, W, which is provided with a turning and guiding device, as F, preferably like that shown and claimed in my application for a patent, No. 114,623, led December 15,1883, but it may be of any other'form, if desired, as may any and all of the parts heretofore described. This guideFis acted on successively by the pins G,fixed in the frame, as described in the aforesaid application.

Attached to the plate E is a shell, H, provided with ears I, having holes through which passes a pin, J, which also passes through ears K, formed on the plate E. On the opposite side of the shell is another ear, L, through which loosely passes a set-screw,y M, that also passes through a spring, N, of rubber or other material, and into a threaded hole in the plate E. The shell H may either be made in the form shown in Fig. l, with standards H on each side, so as to leave the upper part of the type-bands, Snc., exposed, or it may be made so as to inclose the type-bands, and be provided with slots, through which may protrude the wheels O, for changing the position of the bands, as shown in Fig. 2.

The drums carrying the bands are mounted on a shaft, P, which passes through the elongated holes or slots 7L in the standards H', which shaft has at each end a threaded hole, through which passes a set-screw, Q, whose lower end rests on a projection, it', on the standard H, so that by turning the screws Q, the shaft P may be raised or lowered as desired.

The bands pass under a fixed bar, R, secured in slots in the sides of the shell, and as they pass over the drums on the shaft the screwing in of the screws Q will raise the drums and thus tighten the bands, by which means the lattermay he always kept at the proper degree of tension, and thus they may be always moved by the turning of the drums, and will not readily slip out of place accidentally.

By turning the screw M inward the rubber. spring N beneath the ear L will be compressed, and the type-bands will be projected Vfarther through the type-plate, and thus the position of the letters on the bands may be readily and quickly adjusted with respect to the fixed inscription-plate E, or rather the fixed plate E.

By this construction it will be seen I am enabled to combine type-bands with the selfinking stamp in such a manner that I cannot only readily adjust the tension of the typebands, so as to keep them always at the proper degree of tension to be readily adjusted by turning the drums, but prevent them from accidentally slipping out of place, and can also adj ust their faces through the aperture in the permanent inscription-plate, so that they will always line with the faces of the type on the xed inscription-plate, which combines advantages that have never before been combined in this class of stamps.

In some cases the screws may be screwed IOC into the projections h and have their ends bear on the shafts P. This I should regard as a mere reversal of my plan.

Instead of the shell being,` pivoted on one side, a spring and ear similar to those shown at N L may be employed, as shown in dotted lines in Fig. 2; but I prefer the arrangement shown.

For convenience in making the claims I shall designate the device carrying` the changeable type as the movable type-carrier.7

l. The combination, with a permanent inscription plate, of a movable typecarrier d yieldingly connected thereto, a spring between the two, and means, substantially as described, for compressing the spring to adjust the inscription-plate and type-carrier with respect to each other, substantiall y as dcscribed.

2. The combination, withv a permanent inscription-plataof a movable type-carrier having one side hinged to the plate and the other secured thereto by an adj ustinglscrew, sub stantially as described.

3. The combination of the supports of the upper bearing of the type-bands of ahandstamp, with set-screws at each end of said bearing, constructed and arranged to regulate the position of said upper bearing with respect t0 the lower bearing thereof, substantially as described.

In testimony WhereofI afx my signature, in presence oi' two' witnesses, this 22d day of July, 1884.

BENJAMIN B. HILL.
